Billy Jack Haynes turns heel on a broadcast of Portland Wrestling during a six-man match pitting him, Rip and Larry Oliver against The Grappler, The Equalizer and Brian Adams, as the result of a misunderstanding between Haynes and the Olivers.[1] Following the match, Haynes cuts an intense promo against the fans of Portland, his hometown, blaming them for the failure of his fitness gym and a rival promotion he had owned, the Oregon Wrestling Federation, by not supporting either business

1 - In the main event of WrestleMania VI, the Ultimate Warrior pins Hulk Hogan to win the WWF Heavyweight Championship; within the confines of the WWF, it is Hogan's first clear and clean pinfall loss since his return in 1983 (and one of less than five he'd have during all of his combined stints in the WWF, dating to 1979). Also during the event, André the Giant turns face after he and Haku (as part of the Colossal Connection) lose the WWF Tag Team Championship to Demolition, and manager Bobby Heenan, blaming André for the loss, slaps André; André retaliates by slapping Heenan and then stopping Haku's attempted sneak attack. André's match marks the last time he will compete as an active wrestler in a North American wrestling ring for any organization, as his physical health was continuing to decline

4 - Brutus Beefcake suffers near-fatal facial injuries in a freak accident in Lutz, Florida when a parasailer crashes knees-first into Beefcake's face after the parasailer's driver mistakenly takes a cue to take off. Beefcake later undergoes surgery to reconstruct his face, with eight steel plates, 40 screws and over 100 staples inserted into his head to allow every bone in his face to heal. As a result of the injuries, Beefcake's in-ring career is put on hold for nearly three years. Beefcake's injury is announced on the WWF's syndicated programs, a rare break of kayfabe at the time (as he was one of the WWF's most popular and prolific stars of the time, and that on television his match with Curt Hennig at SummerSlam for the WWF Intercontinental Championship was being heavily hyped)

Sgt. Slaughter returns to the WWF after a six-year absence, and is repackaged in a radically different role from his usual pro-America, patriotic character - that as a traitor heel, supportive of Iraq as part of the Untied States-led Operation: Desert Shield (later, Operation: Desert Storm) and efforts to remove Saddam Hussien from power. Slaughter's gimmick made him wrestling's most hated individuals, as many of his promos would praise Iraqi forces while completely denouncing America, and was one of the most controversial gimmicks in professional wrestling to that time
